Step-by-step explanation:
The conditional probability that the carbon emission is beyond the permissible emission level and the test predicts this is given by:
a. 0.2975.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which:
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, we have that the events are as follows:
- Event A: Carbon emission beyond the permissible emission level.
- Event B: Test predicts this.
We have that 35% of the units have carbon emission beyond the permissible emission level, and the test is 85% accurate, hence:
Then:
Which means that option a is correct.
